I wind up pulling about 600 pounds out of my payload before I even start on the trailer. 350 pounds me/wife/dogs, 150 bed rolltop, 100 pounds side bars. Then there is what goes in the bed: generator, grill, inflatable kayak, "stuff" for another 200 pounds. My payload that starts out at 1820 is now down to 1,000.

The trailer dry hitch weight never includes trailer options, battery, propane tanks, the effects of what you load in the trailer. I think you could add another 200 pounds to the dry hitch weight quite easily. Don't forget the weight of the weight distribution hitch.

My guess is that you will be over your payload capacity. But, you now have enough information to figure it out for yourself.

If the 663 is even accurate.....633+ 2-30 pounders = 110 + battery @ 42 = 785. I'd guess another 200 at a minimum for anything in the trailer ahead of the axles less the offset of stuff behind the axles.

I would anticipate the hitch weight to come in around 1000lbs.

I would agree, if not more.
Let's not forget weight distribution hitch and sway control.

Every TT needs a 450 Dulley to make everyone feel safe to be on the highway with you. You should be OK, just drive with extra caution and stopping distance. I can tow a hell of a lot faster than I can stop. Just don't.
